The Iridium communication satellites have a peculiar shape with three polished door-sized antennas, 120° apart and at 40° angles with the main bus.
Occasionally, an antenna reflects sunlight directly down at Earth, creating a predictable and quickly moving illuminated spot on the surface below of about 10 km diameter. To an observer this looks like a bright flash, or flare in the sky, with a duration of a few seconds.
This app displays in real-time where is each Iridium satellite, predicts when these flares will occur from the observer's position and allows from the 3D locator, locate the exact point in the night sky.
